Abstract

L-threonine or L-isoleucine is produced by culturing a bacterium which belongs to the genus Escherichia and has an ability to produce L-threonine or L-isoleucine, and wherein expression of a threonine operon is directed by its native promoter, and from which at least a leader sequence and an attenuator are deleted, in a medium and collecting the L-threonine or L-isoleucine from the medium.
